"An object of the invention is the provision of a heating device of the kind described which is alike easily assembled and installed in either the wall of old or new buildings.

Still another object of the invention is the provision of heating apparatus'o'f the kind described, which, when in place, adds ornateness to the wall in which-the apparatus is installed. a

Another object of the invention is the provision of a heating device of the kind described ,which is self compensating forexpansion and contraction due to varlations in temperature. A still further object of the invention is the provision of heat exchange devices of the kind described which are inexpensive to manufacture, easily installed, durable, reliable and highly satisfactory for their intended puifoses. I

' any other objectsand advantages of the construction herein shown and described will be obvious to those skilled in the art from -novel construction, arrangement and combithe disclosure herein given. ,3

To this end my invention consists in. the

nation of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings wherein like reference characters indicate like or corresponding parts: 1

Fig. 1 is a front elevational view of the device as it appears when built into the wall of a room, or the like; F Fig. 2 is a section along the line 22 of 1g. 1;

Fig. 3 is a transverse section along the line of Fig. 1 drawn to a larger scale; Fig. 4'is a section along the line 44 of Fig. 3 drawn to a larger scale;

Fig. 5 is a section along the line 5-5 of nates a heat exchange device installed in a wall 11. The device includes. a radiator unit comprising oppositely disposed header tanks 24 connected by horizontally extending tubes 27 Y The device includes a,plurality of plates forming upper and lower sections of a housmg or casing. A bottom plate 23, an inter: mediate plate 22 and an upper plate 12 are positioned adjacent the back portion of the wall 11 to form the rear wall of the casing. 1

The plates 12 and 14 form an independent upper section of the housing or casing which cooperates with a lower section of the casing of which the plate 22 forms a part.

The plate 12 has its ends turned inwardly to form side walls of the housing and then again outwardly to form a flange fitting over the outer face of adjacent studding framing timbers 13. The upper end of the plate 12 is board which usually forms a part of the wall of a room. A quarter round 19 is positioned at the junction of the base board 17 with the flooring 18. For the particular portion of the wall in which the device is installed, a strip 20 is provided to hold the base board 17 securely in position.-\ A base timber 21 is also provided in thebottom portion of the device to providea fastening means for the inwardly turned flange on the plate 23.

-The housing is assembled by first placing the plate 23 at the bottom of the structure and then fastening the plate 22 thereon, the

plates 22 and 23 for this purpose having corresponding overlapping flanges. The plate 12 is projected outwardly at its lower edge to form a flange overlapping the upper edge of the plate 22. It is obvious that the plate 22 can be placed in position or removed by merely tilting the plate forwardly or rearwardly. An suitable means may be provided for fastemng the plate 14 and the grilles 15 and 16 in position. The air to be heated enters thedevice through the lower grille 16 and passes between the tubes 27 and thence upwardly to the top of the housing from which it is deflected by the curved portion of the plate 12.

Heating fluid is supplied to the radiator unit through a feed line comprising a horizontal pipe section 29, a pluralityof Us 30. interconnected by nipples 31, 32, and 35 and a curved pipe section 33. The pi e section 33 discharges into one of the hea er tanks 24 from which the fluid travels through the tubes 27 into the oppositely'positioned header tank 24. A curved pipe section 38 corresponding to the curved pipe section 33 provides an outlet for the fluid from the last mentioned header tank 24. From the pipe section 38, the fluid travels through a plurality of Us 30 which are inter-connected by means of nipples 35 and 39 and thence into a trap 37. From the trap 37, the fluid flows through a pipe section 36 to the point of discharge. The arrangement of the feed and discharge pipe sections as shown permits a considerable expansion or contraction due to variations in temperature without placing any unusual strain or stress upon the various parts.

The tanks 24 are constructed by fastening a U-shaped plate to the side wall portions of the plate 22, the connections between the plates being made water-tight by brazing, weldin or other suitable means. The upper ends 0 the tanks 24 terminate adjacent the upper edge of the grille l6 and extend downwardl and rearwardl terminating adjacent tie back wall and opposite the lower edge of the grille 16, the radiator unit being of substantially the same depth as the rille. The radiatorunit comprisin the tan s 24 and the tubes 27 is thereb inclined downwardl and rearwardly ma ing access to the pipe fittings easy upon removal of the grille 16 The tubes 27 are arranged in parallel relation with the spaces between the individual tubes inclined upwardly and rearwardly so that air in assing through the grille 16 in a generally iorizontal direction strikes the tubes and is deflected upwardly and rearwardly with the result that the speed of theair is retarded sufliciently to transfer a considerable portion of the heat to the air. The transfer of heat from the tubes to the passing air currents is accelerated by mounting a plurality of transversely extending fins 28 on the tubes.

The device is assembled by first installing the feed and discharge pipe sections and Com necting the radiator unit thereto with the plates 23 and 22 in position. The plate 12 will then be assembled by mounting its lower edge upon the top of the plate 22'an d-pushing it backwardly into position. The grilles 15 and 16 and the front plate 14 canthen be installed. The device is especially adapted for radiator units of considerable length wherein the expansion or contraction due to vafiations in temperature will be considerab e. I

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departin from the spirit of my invention; hencefi do not wish to be understood as limiting myself to theexact form, construction, arrangement, and. combination of parts herein shown and described or uses mentioned.
